Community Builder How-To's
Community Builder is a Joomla component that controls the registration and user fields of the site. Community Builder displays the tabs with user data in the user profiles, it also allows you to add additional user fields, or delete fields that are already there. (Note, rather than deleting fields, you can simply un-publish them, which will make it easy to get them back if you change your mind.) Community Builder also allows you to create lists (such as a list of reunion attendees) that can be displayed in the front end.
